Sheryl Sandberg: We could've addressed Cambridge Analytica years ago

Facebook COO Sheryl Sandberg admitted Friday that the Cambridge Analytica data breach came to Facebook's attention two and a half years ago, in December of 2015, but the company failed to take the same security steps they are now.

"We could've done this two and a half years ago," Sandberg admitted. "We thought the data had been deleted and we should have checked. They gave us assurances and it wasn't until other people told us it wasn't true ... We had legal assurances from them that they deleted it. What we didn't do is the next step of an audit and we're trying to do that now"
